Description
Full text: A careful layer by layer measurement of the specific activity of 137Cs in the soil is confronted with prediction based on the diffusion-convection equation, applying a boundary condition that - unlike the boundary conditions employed so far - conserves the deposited activity over time in case of very long half lives of the deposited nuclides. From the fit, the deposits from the atmospheric nuclear weapon tests and the Chernobyl accident are very well reproduced. The diffusion constant and migration speed based on the analysis are given.
